Question

In the following excercises, assume that upward is the positive
y-direction.
1. Consider a basketball player who is jumping upward and
accelerating downward at g=10 m/s^2. Assume that her initial
vertical velocity is 10 m/s. On the graph, draw a line that
represents her velocity during the period when she is traveling
upward.

2. On the graph, draw a line that represents her velocity during
the period when she is traveling downward from the poin of greatest
height above the jump point.

THESE ARE BOTH SUPPOSED TO BE VELOCITY VS. TIME GRAPHS.

3. What will be the numerical value and sign of the slope of the
1st graph?
4. " the 2nd?
